Abstract

PURPOSE:To improve the convenience of use of the telephone set through the utilization of a magnetic disk by reading a telephone number recorded on the magnetic disk and outputting a singnal corresponding to the telephone number to a telephone circuit. CONSTITUTION:With a magnetic disk loaded to a disk driver 7, a control track being a telephone number registration track is read. The read telephone number and destination name are displayed on a cathode ray tube 3 so as to discriminate whether or not the system is in the communication standby state. When the communication standby state is discriminated, an electric signal corresponding to the telephone number is outputted directly to the telephone circuit to able to receive a phone call and writes the communication recording at the same time. When it is discriminated that the system is not in the standby state, whether or not new registration is to be applied is inquired about the user and in the case of YES, a ten-key input of the telephone number is written on control track.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to telephone transmission equipment, and more particularly to automatic telephone dialing and transmission recording using magnetic disks.

<Prior Art> In recent years, still image videophones have been put into practical use for general households.

In such a still image videophone, an optical image (such as a sender's face) is converted into a still image signal by an image sensor on the transmitting side, and this still image signal is subjected to AM modulation, for example, and then transmitted to a general subscriber telephone line. On the receiving side, the image signal transmitted via the telephone line is reproduced on a cathode ray tube.

In the above-mentioned still image videophone, the image signal is converted into sound and transmitted over a telephone line, so the still image can be recorded by recording this still image transmission signal on an audio tape. Therefore, it is now possible to record still images of faces and pictures sent by the other party on the phone, as well as the contents of telephone conversations on audio tape, and to transmit still images that have been previously recorded on audio tape. It has become.

<Problems to be Solved by the Invention> As described above, recording still images and conversation content in a still image videophone improves usability, but when audio tape is used as a recording medium,
There are problems in that it is cumbersome to locate the required recording section, and it is inconvenient to carry and store.

On the other hand, electronic still cameras have been put into practical use as media for recording still images, and these electronic still cameras record still images on a small (47 mm diameter) magnetic disk called a still video floppy that is housed in a cartridge. It is supposed to be done.

When recording still images on the above-mentioned still video floppy, tracking of the playback head makes it easy to find the beginning of the recorded section, and it is also possible to record audio on the same floppy, and it is also more efficient than audio tape. It also has the advantage of being easy to carry and store.

Therefore, the present invention is based on the premise that a magnetic disk is used as a recording medium for telephone content (still images or audio in a videophone call, etc.), and aims to improve the usability of a telephone by using a magnetic disk.

<Means for Solving the Problems> Therefore, in the present invention, a telephone number is recorded on a magnetic disk, and the prerecorded telephone number is read by setting the magnetic disk, and a signal corresponding to the telephone number is transmitted. A telephone transmission device configured to output to a telephone line is provided.

Further, the telephone transmission device is configured to record on the magnetic disk a communication record with a telephone number recorded on the magnetic disk.

Furthermore, the video signal or audio signal prerecorded on the magnetic disk is output to a telephone line, and the video signal or audio signal transmitted via the telephone line is recorded on the magnetic disk.

Further, the content recorded on the magnetic disk is output to the telephone line by sound output from a speaker to a transmitter of the telephone.

<Operation> In other words, the phone number of the person you are trying to call is stored in advance on a magnetic disk, and when this magnetic disk is inserted, the phone number is automatically read out and this phone number is connected to the phone line. A signal corresponding to the number is output and a call is made to the desired party, so even if you do not remember the telephone number, you can make a call without fail.

Additionally, when a phone call is made using the telephone number recorded on the magnetic disk, the communication record of that telephone call (for example, the number of communication times, the time and date of the communication, etc.) is recorded on the magnetic disk, so that the communication record for each caller is recorded. can be managed using magnetic disks.

Furthermore, by setting a magnetic disk, important parts of the conversation after a telephone call can be recorded on the same magnetic disk, and if the telephone call is a video call, images can be sent and received via the magnetic disk.

In addition, although it is possible to directly output the recorded contents of the magnetic disk, including the telephone number, to the telephone line, in order to ensure versatility, we configured it so that it can be done by outputting sound from the speaker to the telephone transmitter. Even public telephones can function effectively.

<Example> The present invention will be explained in detail below.

FIG. 1 shows a still image video telephone 1 that transmits still images via a general subscriber telephone line.

Here, the still image videophone 1 shoots a desired image such as the sender's face or picture through the shadow window 2 using a built-in CCD or image tube, and also shoots a desired image such as the sender's face or picture. is projected onto CRT 3.

Then, the cathode ray tube 3 is projected as a moving image on the transmitting side.
A still image desired to be transmitted is selected from among the images using the operation button 4, and this still image is converted into sound and transmitted to the other party connected by a telephone line.

In the case of this embodiment, as shown in the figure, a receiver 5 and a numeric keypad 6 for specifying a telephone number are integrally provided in the still image videophone 1, but the telephone receiver is not a separate part from a normal telephone. It's okay.

Further, in the case of this embodiment, a disk drive device 7 is attached to the still image videophone 1 to drive a magnetic disk (floppy) for recording and reproduction, and a predetermined magnetic disk is set in this disk drive device 7. This makes it possible to selectively record still images and normal conversations that have been converted into sound and transmitted via telephone lines. The magnetic disk is a small size (for example, 47+ am in diameter) that is housed in a cartridge (hard case).
Preferably.

Further, by registering a telephone number on the magnetic disk, dialing is automatically performed. In other words, one telephone number can be recorded on the control track of a magnetic disk (usually the last track, in which the comprehensive program of the magnetic disk is written without any external recording). By reading this control track when the magnetic disk is installed, a pre-registered telephone number is read out at the same time, and an electrical signal (or optical signal) corresponding to this telephone number is automatically output to the telephone line. It looks like this.

To briefly explain such automatic dialing control according to the flowchart in FIG. The control track, which is the number registration track, is read.

Then, in the next step 2, it is determined whether or not a telephone number is registered in the read control track. If it is determined that the telephone number is registered, the process proceeds to step 3. The telephone number and the name of the other party are displayed on the cathode ray tube 3, and in the next step 4 it is determined whether the communication standby state is established.

The communication standby state is, for example, a state in which the receiver 5 has been picked up and no communication has been made yet.When it is determined that the communication standby state is in progress, it is assumed that there is an intention to make a call, and the still video 13 By proceeding to , an electrical signal (or optical signal) corresponding to the telephone number read from the control track is output directly to the telephone line, and a call is made in the same way as when the telephone number is specified using the numeric keypad 6. At the same time, the communication is recorded. Write.

On the other hand, if it is determined in step 2 that the telephone number has not been registered, the process proceeds to step 6 and displays on the cathode ray tube 3 that the telephone number has not been registered. Then, in the next step 7, the user is asked whether or not to perform new registration, and if YES, in step 10.11, the numeric keypad input of the telephone number is written in the control track,
to output the phone number to the phone line. If no new registration is to be performed in step 7, proceed to step 8 to determine whether or not the communication standby state is established.If the communication standby state is not established, the process ends, but if the communication standby state is established, the process proceeds to step 9. To make it possible to use the numeric keypad manually in the same way as when making a normal phone call.

In this way, if one telephone number is registered (recorded) for each magnetic disk in advance, dialing can be performed automatically by loading the magnetic disk into the disk drive device 7. Therefore, for example, if you prepare a magnetic disk for each person you call frequently, record the phone number of the other person on each, and write the name of the other person registered on each magnetic disk, you can use a magnetic disk exclusively for the person you call. Selectively install a disk drive? i! 7, you can definitely make calls. Therefore, you can make a call even if you do not remember the telephone number, making it easier for young children and the elderly to make calls.

In addition, magnetic disks can record still images that you want to transmit via telephone lines, still images that have been transmitted, and parts of conversations, so each person you call can have a corresponding magnetic disk. You can record phone calls such as still images and audio. Therefore, for example, a salesman can prepare a magnetic disk with a registered telephone number for each customer and use this magnetic disk to automatically dial, while also recording information such as visit schedules and order management on the magnetic disk. The above management can be performed for each magnetic disk.

It is also possible to continuously play music recorded on a magnetic disk in advance as background music during a conversation.

Furthermore, in addition to still images and audio, by automatically dialing using a magnetic disk, communication records (for example, the number of communications with a specified destination, the date and time of communications, facsimile transmission, etc.) are automatically recorded on the magnetic disk. You can also record updates.

It is possible that the memory capacity decreases while making a call, making it impossible to record the contents of the communication (still images and audio).In such a case, replacing the magnetic disk will reduce the memory capacity. At the same time, it is desirable to automatically register the telephone number of the other party during communication on the replaced magnetic disk.

In the above embodiment, a magnetic disk is prepared for each recipient and a telephone number is registered in each. However, a single magnetic disk is recorded with multiple recipient's phone numbers, and a selection is made automatically from among them. It is also possible to dial.

That is, by loading a magnetic disk into the disk drive device 7, all telephone numbers recorded on the magnetic disk are read and displayed on the cathode ray tube 3.

Then, a desired telephone number is selected from among the plurality of numbered and sequentially recorded telephone numbers by operating the numeric keypad 6 or by using a touch sensor provided on the cathode ray tube 3. Specify the person you want to call from the list and have it dial automatically.

In addition, multiple faces of the other party are recorded on a magnetic disk in pairs with the telephone number, and when selecting the other party, all the recorded faces are projected onto the CRT 3 and a call is made from among them. It is also possible to select the face of the person you want and have it dial automatically. This allows a salesperson, for example, to have multiple phone numbers for customers and a message (picture) to convey.

It is also possible to record audio (audio) on a single magnetic disk, and when the magnetic disk is inserted into the device, it can be used to automatically send messages to customers one after another. Furthermore, a plurality of drive devices may be built in, and the magnetic disks for recording telephone numbers and the magnetic disks for recording pictures and sounds may be shared.

By the way, since the above embodiment has a configuration in which a magnetic disk is attached to the still image videophone 1, it is inconvenient to carry and difficult to use on the go. Therefore, we standardized the still video floppy (magnetic disk) used in electronic still cameras and the magnetic disk used for automatic telephone dialing and recording in still image videophone 1 as described above, as shown in Fig. 3. As shown, the electronic still camera can be configured to automatically make phone calls and record the contents of the phone calls.

The electronic still camera 10 shown in FIG. 3 is configured to perform electronic still video shooting, which is its original usage, and record the still video (still image) on a still video floppy (magnetic disk) 11. Convert the recorded contents of floppy 11 into an audio signal and send it to speaker 1.
It has the function of outputting sound from 2.

Here, a telephone number is registered in advance in the control track of the still video floppy 11 as in the case of the still picture videophone 1, and this telephone number is read out by operation on the electronic still camera 10 side. . Then, the speaker 12 amplifies and outputs the sound corresponding to the read telephone number, so if the speaker 12 is brought close to the transmitter 14 of the telephone 13 in advance, the sound corresponding to the telephone number output from the speaker can be amplified. The sound is picked up by the handset 14 and automatically dialed.

Also, like this, the electronic still camera ■0 has a speaker 12
If it is equipped with a telephone number, it can be configured to output not only a sound corresponding to a telephone number, but also a sound signal corresponding to a still video image. It is also possible to transmit already-finished still videos from public telephones over telephone lines, making it convenient to transmit still images from the interview site.

Even when using the electronic still camera 10 in this way, instead of recording one telephone number on each still video floppy 11 (instead, a plurality of telephone numbers may be recorded and selected).

Further, the electronic still camera 10 may be provided with a ROM and a telephone line signal output terminal, so that the electronic still camera 10 can directly output a signal corresponding to a telephone number or a still image signal to the telephone line. In this case, a stationary still image videophone as shown in FIG.
Use it as a playback medium.

Furthermore, by using the speaker 12 of the electronic still camera 10 as a microphone, or by providing a separate microphone, the sound from the telephone receiver is picked up by the microphone, and the still video floppy 11
It may also be possible to record the information in

Here, an example of a display on the liquid crystal display section 15 of the electronic still camera 10 will be described with reference to FIGS. 4 to 7.

FIG. 4 shows a display state during normal still video shooting, in which a photographed track block and the shooting date and time are displayed below it. FIG. 5 shows the display when the telephone number recorded on the control track (track No. 52) is called, and the track block of the control track and the called telephone number are displayed. If a plurality of telephone numbers are recorded in each track, the called telephone number and the track Nα in which the telephone number is recorded are displayed. In addition, when displaying a telephone number, it is desirable to simultaneously display a simplified name of the other party of the telephone number.

Also, Fig. 6 shows the display when a still video (still image) or a recorded audio signal is being transmitted via a telephone rotating line, including the status of the track being transmitted, the transmission status display (OK), Transmission start display (START).

A transmission end indication (END) is given.

Furthermore, Figure 7 shows the RO built into the electronic still camera IO.
This is the display when outputting the phone number via M,
The ROM address and phone number are displayed.

<Effects of the Invention> As explained above, according to the present invention, a telephone number recorded in advance by setting a magnetic disk is automatically dialed, making it possible to make a call easily and without error. At the same time, by recording video, audio, and communication records on a magnetic disk that records telephone numbers, it becomes possible to record telephone calls for each callee. In addition, rather than outputting telephone numbers directly to the telephone line (and allowing the handset to pick up the telephone number through a speaker, even if it is a public telephone, automatic dialing and recording on a magnetic disk can be done). This has the effect of making it possible to transmit still images and audio.
